Quantitative evaluation of the effect of buffer pressure on well output

Journal Article:

Abstract

In the examples of the Pashninskiy and the Usinskiy fields of the Komi ASSR, a method is presented for determining the possible increase in output of a gusher well on decrease in the buffer pressure. A quantitative evaluation of this increase is presented. The essence of the method is construction of a nomogram for characteristics of a gusher lifter and indicator diagrams of the wells combined in one figure. Mutual intersection of the characteristics and diagrams corresponds to the steady-state operating mode of the bed-well system. Cases are examined of productivity 10, 25, 50 and 100 m/sup 3//day of the MPa for the Pashninskiy and 25, 50, 102 and 200 m/sup 3//day of the MPa for the Usinskiy fields. Despite the broad range of well productivity, and also the significant difference in fields according to gushing conditions, increase of the well output for 0.1 MPa of decrease in buffer pressure differs little. In the interval of buffer pressures 2.00.5 MPa, the specific increase of output from decrease in buffer pressure is very significant and is 7-10 m/sup 3//day. The findings convincingly proved the expediency of using systems of oil and gas recovery at new fields with possibly low pressure in  More>>
